All blocks and head castings are NOS GM components. The 4.500" bore center platform (standard SBC is 4.400" bore center) will allow the user to machine the blocks up to 4.250" bore while maintaining a minimum wall thickness of .225" on the thrust side. You can build the big bore short stroke combinations that have been so popular when high HP is a requirement!

All blocks that we have in stock have already had the SB2.2 lifter pattern machined into them to compliment the cylinder heads that we have available. The blocks are made of compacted graphite.
